💸 International money
How international money transfers work
The chain behind a cross-border payment — funding, conversion, messaging, correspondent banks, and payout — and why a low headline fee is not the same as a low total cost.
International transfer fees explained
Every charge that can eat into a cross-border payment — transfer fee, funding fee, lifting charge, intermediary and recipient fees, withdrawal and return costs — and how to add them into one total effective cost.
Exchange rates and hidden FX markups
What the mid-market rate is, how TTS/TTB and spreads work at Japanese banks, and how to calculate a provider’s exchange-rate markup so the hidden cost stops being hidden.
Mid-market rate versus bank exchange rate
Why Google, the ECB, Wise, banks, cards, cash counters, and merchants all show different exchange rates for the same currency pair — with worked yen examples.
SWIFT transfers explained for Japan
What SWIFT messaging is, how correspondent banking and BIC codes work, why fees appear along the way, how gpi tracking helps, and when a SWIFT wire is genuinely necessary.
Correspondent and intermediary bank fees
Why intermediary banks deduct fees, how routing decides who is in the chain, why the deductions are hard to predict, and practical ways to reduce the uncertainty.
OUR, SHA, and BEN transfer fee instructions
What each fee instruction means, who pays, why choosing “OUR” does not always guarantee the full invoice arrives, and what this means for paying invoices and tuition.
International transfer times and delays
Why an “estimated” arrival is not a guarantee — weekends, bank holidays, cut-off times, compliance reviews, intermediaries, and recipient-bank processing all move the real delivery date.
International transfer limits in Japan
How Type I and Type II funds-transfer providers, the ¥1 million threshold, bank caps, and customer-specific limits interact — and what to use when you need to send more.
Source of funds and purpose of a transfer
What “source of funds” and “purpose of transfer” mean, which documents prove salary, savings, inheritance, sale proceeds, or business income, and why a vague purpose invites questions.
Currency risk and when to convert money
How holding a foreign-currency balance exposes you to timing risk, why matching income and expenses reduces unnecessary conversion, and how to avoid turning a payment need into speculation.
Weekend exchange-rate markups
Why some providers add a charge when currency markets are closed, how Wise and Revolut treat weekends differently, and how to time a conversion to avoid the surcharge.
How to compare international transfer quotes
A repeatable, same-time methodology for comparing providers on the recipient amount for an identical total sender debit — the only fair way to find the cheapest route for your transfer.
Dynamic currency conversion (DCC) explained
What DCC is at merchants and ATMs, why paying in your home currency abroad usually costs more, and the simple rule — choose local currency — that saves money almost every time.

Why there is no context-free cheapest provider, how cost changes with amount and corridor, and a same-time method to find the cheapest route for your specific transfer.
How to make a large international transfer from Japan
Sending more than ¥1 million: Type I services and banks, negotiating the FX rate, preparing source-of-funds documents, verifying the beneficiary, timelines, and when to involve a professional.
Emergency international money transfers
Getting cash to someone fast and safely: cash-pickup networks, tracking codes, recipient identification, and the fraud checks that matter most when there is time pressure.

The order of inquiry for getting paid from abroad — domestic payroll, platform receiving details, or a Japanese bank SWIFT account — plus the records to keep and why leaving salary abroad does not make it tax-free.
